We measured bone mineral density (BMD) in 128 men and 143 women, aged 22-90, by dual energy X-ray absorptiometry (DEXA) and quantitative ultrasound (QUS). We found reduced bone mineral density in relation to age as measured both by DEXA and QUS. There was a correlation between 0.28 and 0.52 in men and between 0.53 and 0.77 in women when comparing DEXA and QUS measurements. When including only persons with low bone mass, the correlation was less.
我们通过双能X线吸收法(DEXA)和定量超声(QUS)对128名年龄在22至90岁之间的男性和143名女性进行了骨密度(BMD)测量。我们发现,通过DEXA和QUS测量,骨密度均随年龄增长而降低。比较DEXA和QUS测量结果时,男性的相关性在0.28至0.52之间,女性的相关性在0.53至0.77之间。仅纳入骨量低的人群时,相关性较低。
